The mineral acid name 'sulfuric acid' is ambiguous because is does not adequately distinguish between: the compound H2SO4 'sulfuric acid', concentrated 'sulfuric acid' and 0.1 molar (diluted) 'sulfuric acid'.

It is not possible to (economically) concentrate dilute sulfuric acid.XH2O into sulfuric acid the compound and the world's most important inorganic chemical by tonnage.
